A laboratory at the Illinois Institute of Technology is using fiber diffraction to examine tissue structures in the human brain and heart, as well as in T. rex fossils. Few researchers use this type of X-ray diffraction because of the time and labor required to complete experiments, the researchers have resolved images of the fine threads of collagen fibrils in connective, neurological and dinosaur tissues to one-billionth of a meter. During the 68th Annual Meeting of the American Crystallographic Association, they will explain their work.

Fossils of a new genus and species of an ankylosaurid dinosaur—Akainacephalus johnsoni-- have been unearthed in Grand Staircase-Escalante National Monument in southern Utah, U.S.A., and are revealing new details about the diversity and evolution of this group of armored dinosaurs.

This stamp, featuring the 1993 movie Jurassic Park’s iconic Tyrannosaurus rex, was released by the U.S. Postal Service in 2000 as part of a souvenir sheet “Celebrate The Century: 1990s.” Legendary movie-poster artist Drew Struzan illustrated the stamp. He is known for his more than 150 movie posters, including all the films in the Indiana Jones, Back to the Future and Star Wars film series.

Dinosaur-age fossilised remains of tiny organisms normally found in the sea have been discovered in inland, arid Australia – suggesting the area was, for a short time at least, inundated by sea water 40 million years before Australia’s large inland sea existed.

An international team of scientists has concluded the asteroid that smashed into Earth 66 million years ago not only wiped out the dinosaurs, but erased the world’s forests and the species that lived in trees. The researchers say only small ground-dwelling birds survived the mass extinction, profoundly changing the course of bird evolution.

Comparing how the chromosomes of modern-day birds and turtles are structured can help scientists figure out how dinosaur genomes might have looked. An Iowa State University scientist contributed to an international research team that recently published its findings reaching back through 260 million years of genomics.

Every 405,000 years, gravitational tugs from Jupiter and Venus slightly elongate Earth’s orbit, an amazingly consistent pattern that has influenced our planet’s climate for at least 215 million years and allows scientists to more precisely date geological events like the spread of dinosaurs, according to a Rutgers-led study. The findings are published online today in the Proceedings of the National Academy of Sciences.

Silvisaurus condrayi has made a return to the KU Natural History Museum in a new, more complete form, accompanied by an interactive display that includes stunning depictions of the dinosaur and its environs.
